Large, elephant-like posthumans who eventually regained their intelligence.
Diabolus ex Machina: They were quickly advancing as a species after regaining their intelligence — until an ice age unexpectedly wiped them out.
Gentle Giant: Described as such by the Author. These guys were absolutely huge, but they were actually a kind and intelligent species whose lives were tragically cut short by an ice age.
Honorable Elephant: The Titan species strongly resembled elephants and were described as one of the best candidates for the reemergence of civilization. Sadly, they were wiped out by an ice age before that could happen.
Kaiju: Adult Titans measured 40 meters long, making them even bigger than Blue Whales.
Mammoths Mean Ice Age: Inverted; an ice age was responsible for the extinction of these mammoth-like post-humans.
Multipurpose Tongue: The Titans were a variant with multi-purpose lower lips, which hung down like elephant trunks and were dexterous enough to manipulate objects.
