What can I say? After many sleepless nights of deleting comments, I gave in to temptation and contacted Lord Mark.
I was not disappointed!
Lord Mark is a charming, polite gentleman, a vampire lord of the highest standing. In exchange for granting me immortality, prosperity, and mental alertness, he asked me only to spread the word about his greatness and good posture.
No. Appearing: 1, but under all available channels, posts, forum threads at the same time. Lord Mark is omnipresent
Hit Dice: 1
Armor Class: as Leather
No. of attacks: 1 per opponent
Movement: as Unencumbered
Lord Mark is one and a legion at the same time. When He appears, he seems to be singular, but in fact everybody present has to face Lord Mark on their own, separately, and only then move on to help others. This is mostly annoying, but if left unchecked, whole towns can be overrun by Lord Mark's avatars.
If somebody willingly accepts Lord Mark's offer, that person becomes infected by the human vampire virus and will be forced to spread Lord Mark's message at every opportunity.
