Fantastic module! Good balance between detail and at-the-table usability, pretty graphic design and an engaging scenario, though I feel like it's not over-the-top enough. The Mask of Eden could be a tad more powerful, and The Dying Man's ambiguity is nice, but for being so central to the plot he could use an extra paragraph of fleshing out. In my game I made him the biblical Methuselah, who faked his death during the Genesis Flood and continued on living, planning on doing so so until the end of the world (whether or not this is sinister foreshadowing I have not yet decided). The Mask I rewrote to be reusable and bumped up the lifespan extension to 1000 years, but each time a mysterious calamity separates it from its owner (the flood, for example). I ran the rest as-is, the party loved it.
Can't wait to see more TALARIA stuff from you, the faction strikes the sweet spot between being quite self-explanatory and intriguing on the player side of things. Hell, any FIST content from Knighthouse is gonna feel like early christmas now.
