David Crockett never died at the Alamo!
He died at Atagahi.

After moving to rural Tennessee, the three Dolor siblings accidentally open a mysterious gate to an enchanted forest, unleashing mythological creatures into their world. Guided by the ghost of David Crockett, they must journey into the dangerous magical realm to find the legendary Lake Atagahi, confront their own failings, and discover a way to close the gate before their family—and their world—is consumed by the forces they have set loose.
