Cathume's Kudos:
Rhaeg
Firstly, I've always dug the stoic hero vibe, but it was always the angst that got to me. Rhaeg is well developed beyond that--get past his first layer and he's actually a deep and incredible character with serious purpose. An enemy of the state, but for all the right reasons, Cathume joined his rebellion and Rhaeg's been a fast friend since.
Kera
My repeat offender on the Kudos lists, Kera took Cathume into the Hin village and even bought her house once she'd left Cordor. A constant support, Kera's been like a sister to Cathume, and always there when she needed it. Cathume's best friend, hands down, Kera's kindness mixed with a dark past creates a complex character who's a joy to learn more about... especially as she navigates the unseen dangers and frustrations of Hin politic.
Ruby & Mykthal Silverbeard
The folks at the Fool's Clover had hired Cathume shortly before she absconded from Cordor. They were fun, witty, and pretty kind to her--even when she handed them her key not even a week later. They even took her adventuring and treated her like she'd never left. Some real pals, these two!
Bhando Muddletoes
I don't know how he got himself into so much trouble, but he's always been kind and sweet towards Cath. As a bonus, his recent enslavement has given Cathume the urge to take action in a conflict she might not otherwise have been a part of.
Avernala's Kudos:
Rauvlin & Shairin Barrith
Rauvlin took Avernala in when she was wandering about Underdark. She shaped her up, had her join Barrith for her own survival. Not only was Avernala's character changed by the idea of camaraderie among the Drow (as her new matron La'laskra demands), but Rauvlin has been a source of support in seeing Avernala grow to be a potential priestess. Shairin, being the matron, also supported her learning, and has been teaching her through the use of pain how to augment her abilities and become the kind of Drow she needs to become in order to survive.
Jadiira Khal'naust
In a word: Fabulous. The dark and merciless archpriestess inducted Avernala, and while each encounter has been small, Jadiira has always had significant RP around her, at all times. One of the most developed Drow I've ever seen, Averna has a lot to learn if she's to keep up with her.
Girg'lax
The little Imp and Averna only met a couple days ago, but he's been a witty companion with extremely powerful magic abilities. He also knows when danger's near, and whether he's flying away from the source of it or whispering in Averna's ear, Av is usually good on picking up the clues.
Axe
Haven't actually met, met you. Came up randomly, threw some awesome potions at me, and then walked away. Thanks again.

Talfeiniir Serenthaal
After the fall of his house, he still showed grace and style when talking with Avernala. He was even pretty deft around the subject of her La'laskran worship, a bit of a hot-button issue.
Elise Na'dar'zul
Chills. Just chills. Nobody gets Averna heated like Elise does, and it may be the death of her. Elise brings out the best conflict between Avernala's cultured self, and the desire to be well and truly free. A particularly interesting conflict on the cusp of her Acolytehood.
