A strong cultural deep-dive with a confident narrative arc (origin → daily life → kingdoms → cosmology → mummies today). The voice is largely on-brand: National Geographic register, specific place names, definitive statements. Most slides need surgical, not structural, edits.
What's strongest: Slide 1's opener ("Guanche means son of Tenerife") and slide 4's split on the conquest (five fought, four allied) are the highlight's best beats. Slide 5's Guayota / Acháman myth is the kind of profound, specific detail that sets Lava Guide apart from generic guidebooks.
What needs work: Two systemic fixes land across several slides: canonical Teide (no article) and the insight-wide number-style rule (digits for all numbers ≥ 2). The guide note on slide 6 under-delivers on practical value — it's the one place in the highlight that closes the loop from history to what the reader does next, and it currently stops at a one-liner. Mummy-count figures on slide 6 are freshness-sensitive and should be verified before ship.
Optional recommendations
Flag before ship: verify the Guanche mummy repatriation numbers on slide 6 against MUNA's public record (two mummies returned from Argentina in 2003; three from Madrid in 2011). If unverifiable, soften from exact counts to "some" / "more".
Flag before ship: the expanded slide 6 guide note proposes a 90-minute visit estimate and a walk-in cue. Confirm MUNA's current opening hours and whether walk-in is still realistic before publishing. Do not invent hours.
Optional structural tweak: the highlight never closes the loop from story to action beyond the final guide note. Consider whether slide 6's body (currently all mummy-trade history) could end on one forward-looking line — "Today they're home." — to set up the MUNA footer more emotionally.
Persona reactions
Agreement: Pierre, Clara, and Lena & Théo all rate this highlight as rich, confident, and worth the swipe-through — the content earns its slot in the insight. All three also converge on one gap: the ending is intellectually satisfying but practically thin. They've just learned why they care about MUNA; the guide note doesn't tell them how to actually go.
Conflict: Pierre wants concrete logistics on the final slide (walking distance from Santa Cruz centre, parking hint, whether the mummy hall has benches). Lena & Théo want the showstopper cue (which room, photography allowed?) and a time-of-day hint. Clara wants a booking-vs-walk-in answer and a time estimate she can slot into her plan. Same footer, three different asks — all solvable by upgrading the guide note on slide 6 from one line to three.
Persona-driven fixes (priority order):
Expand the slide 6 guide note into a practical MUNA footer: location cue, walk-in vs booking, a 90-minute allowance. Verify hours before publishing.
Fix "the Teide" on slide 5 → "Teide". Canonical across the insight.
Verify the mummy repatriation counts on slide 6 (2 from Argentina in 2003, 3 from Madrid in 2011). Soften if unverifiable.

Guanche means son of Tenerife. It is the name of the people who lived on this island for two thousand years before the Spanish arrived.
Every town name you pass on this island is a Guanche kingdom name. Tacoronte, Adeje, Güímar, Anaga. This is their story.
Proposed
Guanche means son of Tenerife. It is the name of the people who lived on this island for 2,000 years before the Spanish arrived.
Every town name you pass on this island is a Guanche kingdom name. Tacoronte, Adeje, Güímar, Anaga. This is their story.
Why. Applies the insight-wide number rule (digits for all numbers ≥ 2). "2,000 years" also reads faster and looks more authoritative on a small screen than "two thousand years". Everything else already works: the opener is specific, confident, and closes with a strong definitive beat ("This is their story").

The Guanches arrived from North Africa in several migratory waves, Berber in origin. They found a rugged island divided in two by a central massif, with deep valleys at La Orotava in the north and Güímar in the south. They called the island Achinech. They settled in mountain caves, organised in extended family groups along matrilineal lines, raised goats and grew wheat and barley.

Why. "Divided in two" → "split in two" is one fewer syllable and slightly more physical. Merged the final two clauses ("raised goats and grew wheat") into a cleaner list without an Oxford comma and without the redundant "and" linker — tighter rhythm. Keeps all the facts, keeps the "Achinech" detail (a keeper).

The Guanche language went extinct by the early 17th century. But some words remained in use. Gofio, toasted and ground grain, is a Guanche word still at the centre of Canarian cooking today.

The Guanche language went extinct by the early 17th century. Afew words survived. Gofio, toasted and ground grain, is a Guanche word still at the centre of Canarian cooking today.
Why. Swapped "Their main food was" → "Their staple was" to avoid the weak "was" twice in two sentences. In the guide note, "But some words remained in use" is passive-leaning throat-clearing; "A few words survived" is active and three words shorter. The gofio callback stays.

After the last unified king, Tinerfe the Great, died, his nine sons divided the island into nine kingdoms called "menceyatos". Each was governed by a king. The nine kingdoms were Daute, Icod, Taoro, Tacoronte, Tegueste, Anaga, Güímar, Abona and Adeje. Most town names on the island today come directly from those kingdoms.

When the Spanish invaded, five northern kingdoms fought back. Four southern kingdoms chose peace and allied with the invaders. That split shaped the entire course of the conquest.

Why. Insight-wide rule: digits for all numbers ≥ 2. This slide uses "nine" four times and "five" / "four" once each — all converted. The narrative content is strong (Tinerfe, the menceyatos, the north/south split) and is left untouched.

The Guanches believed the Teide was hell. They called it Echeyde. The name Teide comes directly from that word. Inside lived Guayota, demon of evil, locked there by the supreme god Achamán as punishment for abducting Magec, the god of light. The National Park was sacred and forbidden. They mummified their dead using cattle fat and animal skin wrappings, a process called mirlado, preserving skin and muscle for centuries.

Why. Canonical across the insight: Teide, never "the Teide". This is the only instance in the highlight. The myth itself (Guayota, Achámán, Magec, Echeyde) is exactly the kind of profound, specific detail Lava Guide exists to deliver — kept verbatim.

Guanche mummies were commercialised and travelled across continents. Two were sold in 1889 and spent over a century in Argentina before being repatriated in 2003. Three more were returned from Madrid in 2011.

Go see the Guanche mummies with your own eyes at MUNA in Santa Cruz.
Proposed
Go see the Guanche mummies with your own eyes at MUNA,a 10 minute walk from Santa Cruz's main plazas. Walk in, no booking needed. Allow 90 minutes. The mummy hall is the showstopper.
Why. Two things on this slide. (1) The mummy counts on the body are verifiable-in-principle but need a cross-check against MUNA's public repatriation record before publishing — flagged in recommendations. The number-style rule (digits ≥ 2) pushes "Two" → "2" and "Three" → "3". (2) The guide note is the highlight's one opportunity to close the loop from history to action: it currently stops at "go see them". Upgraded to a three-line practical footer covering location, walk-in cue, and a 90-minute visit estimate — addresses Pierre, Clara, and Lena & Théo's shared ask. Opening hours deliberately not invented; verify before publishing.
