Faendal

"I don't like to brag, but I once took down a bear at three hundred yards. In a blizzard."

- Faendal

Faendal is a male Bosmer archer in Riverwood. He and Sven have a rivalry for the love of a local girl, Camilla Valerius. He offers Archery lessons at the Adept level.

Interactions
Faendal is a potential follower if the Dragonborn sides with him by exposing Sven's letter to Camilla or by giving Camilla his own fake letter.

This gains you the gratitude of Camilla as well as Faendal. After completing this quest, you can ask Faendal to follow you and he will readily oblige. If he is encountered before Sven, it is Faendal who will suggest using a fake letter to discredit Sven, mirroring most players' experience.

Faendal's House
Faendal's House is located in Riverwood. Sometimes Faendal will not leave his house, leaving the door in an unlocked state. To fix this, reenter and try again. It is possible to pickpocket Faendals key.

Archery
After taking Faendal on as a companion, it is possible to receive free Archery training. Purchase the next training level up from Faendal, then speak with him to open the trade option. Take back the money paid for training. This can be repeated up to five times per level, up to level 50 in archery.

Pickpocket
With any trainer, you can use the cutpurse perk to pickpocket the money back. The total value of gold affects the success rate.

Another way to steal large sum of money from a trainer is to pickpocket them, put a paralyze potion inside his inventory (Which obviously needs a specific Pickpocket perk called "poisoned" ), then when he is paralyzed wait on sneak mode. As soon as the paralyze effect runs out you can pickpocket the gold without him noticing.

Lockpicking
Faendal's house has an Apprentice level lock. To raise lockpicking, the key to his house will need to be returned, if it was taken. With Faendal following, pick the lock to his house, then go back outside. He will lock it again - resetting it so it may be picked again.

Follower
Faendal seems to have a lawful disposition; if you lockpick your way into residences, he will occasionally say, "You should not be in here" and refuses to enter dialog options preventing the 'trade items' and 'pick up items' commands until you leave the area. Also, if you enter combat with Hold Guards or Imperial Soldiers, he will stop following you and begin attacking you.

Faendal is competent with bows but often prefers to use daggers and swords if given to him. He will use the most damaging bow in his inventory at long range, the most damaging blade available at close range, while at mid range (provided no obstacles) he tends to use any weapon with the highest damage.
