Here is a short blog post about Trellia and the origin of the Skyfin dolphins from the distant future (Ecco universe)
That art is gorgeous, thanks for making that post! With stuff like this and The Last Breath of Elisia are you worried that you might be giving away too much that you might want to cover in a new Ecco game? Or should we treat it as supplementary material? Don't give up on trying to get the IP back. If Twin Peaks can come back after 25 years, miracles can happen.
As a side note, everything from "The Asterite (Helix)" down is hard to read without cursor highlighting because of the background colour, you might want to change that if you can. Next time you also might want to share the upcoming announcement on the board instead of just on Twitter.
