Skyrim:Teldryn Sero

thumb|right|Teldryn Sero without his chitin helmet
Teldryn Sero, a Dark Elf Spellsword, is a mercenary found in the Retching Netch. He can be hired as a follower for 500 gold. 

He wears a full set of light chitin armor, including the cuirass, boots, bracers, and helmet. He carries an elven sword and an elven dagger.

Teldryn knows the Conjuration spell Conjure Flame Atronach, the Destruction spells Firebolt and Flames, and the Restoration spells Fast Healing and Steadfast Ward. His first move in combat is to summon a flame atronach. He usually alternates between using his sword and his Destruction spells dealing fire damage. 

He grew up in Blacklight in Morrowind. He claims he once met Saint Jiub, making him over 200 years old. At some point he moved to Windhelm's Gray Quarter before eventually moving to Raven Rock. According to him, his chitin armor was especially made for him by Grendis Rolovo, one of the finest master armor smiths in Morrowind.

When you first meet him, he may greet you with one of the following lines: 
''"Teldryn Sero, blade for hire. If you have the coin, I'm at your service."
"The best swordsman in all Morrowind is at your service... for the right price."
"Don't pass up on this opportunity, outlander. I'm worth every coin."
"I've got swords, spells and a few other tricks up my sleeve. You'll find I'm full of surprises."'' 
If you don't have enough gold to hire him, he'll reply, ''"Unless you have enough coin on you, I'm not going anywhere."'' If you do have enough gold, he'll respond, ''"Then let's be off!"''

If you have dismissed him and approach him again, he'll greet you with, ''"I was enjoying our travels together before we parted company. I'd be happy to rejoin you for no charge... if you're interested." If you choose to rehire him, it will be free and he will tell you, "Lead the way."''

As a Follower
While Teldryn is your active follower, you can ask him how he ended up on Solstheim. He'll explain, ''"Long story, but I don't see the harm in sharing it with you. My last patron was a true Nord. He was dressed in animal skins, had tattoos on his face... a real traditional type, if you know what I mean. He had an insatiable bloodlust and was extremely stubborn... one of the toughest employers I've ever had."'' If you ask why he continued to work for the man, he'll answer, ''"Simple... he paid well. Very well. Anyway, we'd just cleared a ruined fort somewhere outside of Whiterun and when we got outside, we saw one of them galloping away on horseback. Well, my boss wasn't about to let him get away, so we pursued... on foot, for three days." If you ask him to elaborate, he will continue, "Until we ended up tracking him to one of the largest bandit encampments I'd ever seen. My patron took one look at me, and made the most menacing grin I'd ever seen. At that moment, I knew I'd never see him again. No amount of money would ever be worth that kind of death."''

If you ask him to do something, he'll say, "What do you have in mind?" If you talk to him before giving a command, he'll say, "Did you still want me to help you or not?" If you tell him yes, he'll say, "Very well." If you tell him no, he'll say, ''"You're the boss."'' When you tell him to do something, he'll say, "Right away.", ''"That's not going to happen.", or "I don't care how much you're paying me, there's no way I'm doing that."'' He'll then ask, "Anything else?" If you tell him you need to trade some things with him, he'll say, ''"If it'll help us get moving quicker, sure."'' If you tell him to wait where he is, he'll say, ''"You're going ahead without me? Suit yourself..."'' While he's waiting, he'll say, "You better not be gone long." and ''"Make it quick, I don't like this waiting game."'' If you tell him you want to part ways, he'll say "Oh fine, go on... leave me here. When you decide to return to your senses, you know where to find me." When you exit conversation while he's following you, he'll say, "Right behind you." and "Lead on."
