He explains not being able to do so at earlier levels by claiming he was cursed. BTW, this druid character believes he is really a dragon that can shapechange into a human druid, and not the other way around, for comical effect.

The druid was able to acquire Dracolyte through taint. The other player is a Human Druid7/Dracolyte10 with a young adult red dragon cohort, which was modified from the basic monster entry. I do have one player who is a Half celestial/Wood elf cleric5/Purifier of the Hallowed Doctrine8, with a cohort that is a Half celestial/wood elf cleric5/combat medic2/Radiant Servant of Pelor2 ,so I need to figure out how to apply the half celestial template for them. I don't think I can apply templates to a PC character like an NPC, but if there is a way I would love to know how. I'm trying to figure out if it would be more efficient to control such a character if created as a PC controlled by the DM, or as an NPC.

This NPC is a Human/Lich/Spellstitched/Evolved undead with multiclass Cleric20/Sorceror8/TrueNecromancer14. I know this may sound crazy, but there is one NPC (personality) character that is vital to the plot who rules a city and army of undead, who is allied with the players against other undead and various enemies in the story. I won't list them all but some of them are Libris Mortis, Book of Vile Darkness, Book of Exalted deeds, Heroes of Horror, Heroes of battle, Epic level handbook, Draconomicon, etc. We are using a variety of books, more than just the core programmed into fantasy grounds. I have watched several videos and get the basics, but I have several high level characters in my story that I'm not sure how the best way to enter them into FG would be.

I have the ultimate license, complete SRD, advanced bestiary for templates, and summoned monsters MODS. I have DMed many games in the past in 3.5, including ones this complex and on paper things are fine, but trying to learn FG as a DM for 3.5 seems a bit more involved, which I am ready to deal with, than playing a D&D 5e character. I have some experience with Fantasy grounds playing a low level character in a D&D 5e game with another friend, but no experience with FG using the D&D 3.5 rules set. We are trying to transfer our face to face paper game to FG. I'm trying to run a high level campaign for a friend of mine who is in the Navy, along with a one other player who lives at home with me.
