How is it possible?
Page 92 of the ToA adventure says:
A little over a century ago, Acererak entered Omu and slew all nine trickster gods. He then enslaved the Omuans and forced them to carve out a tomb for their defeated gods. When the tomb was complete, Acererak murdered the Omuans and sealed them in the tomb with their false gods.
So, group A was killed at moment 1. Okay.
group A = Omuans; moment 1 = a little over a century ago
Later in the adventure, it says on p. 165:
After Acererak slew the trickster gods of Omu and enslaved the city, Napaka, the city’s elderly queen, chose not to flee, and instead offered herself as a sacrifice in exchange for the release of her people.
So, person B was killed at the same time. Okay.
person B = Napaka; same time = a little over a century ago
Page 69 of the adventure says:
Seventeen-year-old Princess Mwaxanaré is the oldest living descendant of the royal families of Omu and the primary heir to the fallen kingdom. She and her six-year-old brother Na [...]
So person C was born at moment 2. Okay.
person C = Na; moment 2 = 6 years ago
The same page continues:
Their great-grandmother, Napaka, was the last ruling queen of Omu; their father, Omek, died in a fall, and their mother, Razaan, was killed by pterafolk.
Hm, it looks like his mother (person D) was able to bear children at moment 2. Also, she is a granddaughter of person B. But person B was killed at moment 1.
person B = Napaka; person D = Razaan; moment 1 = a little over a century ago; moment 2 = 6 years ago
The skull in the crystal box belongs to Nepartak, the 10-year-old granddaughter of Napaka, the last queen of Omu.
So, another granddaughter of person B was born at the time of moment 3. That is strange.
person B = Napaka; moment 3 = 110 years ago
How old was person D when she bore her son? 104? Really?
How old was she when she died? Between 104 and 110?
Is this natural for Chultans?
person D = Razaan
