Seems like they're preparing a new part of Time Temple.

kinda, it's mostly an epileptic tree joke out of these two quotes:



if the above is to be taken as an actual quote, it means that seeking the world tree won't lead to evil empresses, and in fact, the "gate to the future" was made by a henchman of the black mage to prevent the empress from doing it, which would mean neinheart was acting the same way the black mage wanted. preventing the empress from gaining more power to fight the BM

Assuming that scene ever happened at all, as Razmos indicated.
