I watched a gameplay video on how to play on Stingle for the Green and Yellow factions – the inability to choose a starting hero completely kills the interest. Because there simply ISN'T one :eek:
You have to build a tavern first, and only then can you play.

Regarding the Sanctuary – the attached screenshot shows the moment when my hero just cleared it out; unfortunately, I don't have an earlier save. The minimap shows where this Sanctuary is located.
