Interesting to learn Morgause & Disgrace are, for lack of a better term, acquaintances. How deep does this relationship go, and how do Unseelie’s peoples/monsters feel about it?
Morgause had no idea who Disgrace was until he literally appeared on her doorstep. He had heard of her, of course, because she was the most famous necromancer on Gaia. He was quite a passionate necromancer himself and wanted to seek her help with training, troops, enchanted weapons, and so on. He was prepared to make serious deals with a powerful kingdom, but he didn't quite know what to expect when he flew into the Unseelie Court for the first time.
Morgause saw a huge fleet of mysterious armed men and undead heading towards her castle and said "oh hell naw", personally running outside to blast them into oblivion. But when she laid eyes on Disgrace, it was love at first sight...well, not "love" exactly, because monsters aren't capable of it. It was more like an intense, all-consuming lust that has gripped her by her shriveled ovaries ever since that fateful day...she thought the Overlord was the hottest thing on Gaia, and she proposed marriage within 10 minutes of meeting him.
Disgrace accepted her proposal, but only in exchange for troops and gold. Morgause gladly handed over a fat load of resources and had an impromptu wedding that night. Unfortunately for her, Disgrace still had business to manage back in the Serkel Desert, so he could not stay and be her king (not that he wanted to anyway). She bid him a dramatic farewell, but said he was welcome back so long as she remained on the throne.
So, yes...Disgrace is legally married to Morgause. She is also married to like 40 other dudes, so that doesn't mean much, but she does consider him her favorite husband because he is the only divine one. Their marriage is only legally recognized in Unseelie Court, other Great Kingdoms won't even acknowledge it.
Some Unseelie people are disgusted by Morgause's marriage to this high-profile terrorist, but most of them are so fatigued and so used to her crazy bullshit, they're just like "Yeah, that's classic Morgie...". Her other husbands are a collection of warlords, crime bosses, and other scumbags, so this is no surprise to them.
As for Disgrace, he hates Morgause. He truly despises her, thinks she's repulsive, and resents every second he has to spend around her. But she's officially his sugar momma, the one with the big money he needs for his operations, and the only Great Ruler who doesn't tell him to fuck off, so he has to play nice with her once in a while. She looks forward to his visits like Christmas morning, meanwhile he's dreading it like a root canal. They have a really funny dynamic imo.
