The secret boss of Skies of Walltestia, who the players elected not to unlock: SHADOW THE UNFORGOTTEN.
Spending every day in the shadow of someone, at their beck and call, at their side but never being seen, well... It would have an impact on you, after millenia.
This boss was going to involve a real life timer, and moving through old, messed up versions of maps that had already been played in the campaign. At certain hp thresholds, rules would flip, like you would have to hit under his AC to hit.
