The Trial of Five-Clawed Guile

Breda, a New Life Herald in Eastmarch, spoke of Rawl'kha's New Life Festival. The residents of Rawl'kha partake in a game where they try to open locked chests, in honor of their thieving god Rajhin. The Vestige travels there and speaks with Tumira, where she will challenge him to open three locked chests, and claim three tokens, Footpad's Coin, Prowler's Coin, and Rajhin's Coin, presenting them to Tumira and winning the challenge.

Walkthrough
Head to Rawl'kha, the capital of Reaper's March, and enter The Outskirts of the town. Tumira will be waiting near a stand for you, and will tell you to open three locked chests in the area. These don't have to be opened in a specific order. The chests include the Novice's Chest, with a Simple difficulty to open, Apprentice's Chest, with an Intermediate difficulty to open, and Rajhin's Chest, with an Advanced difficulty to open. After you've opened these chests and emptied them out of their respectable tokens, you will need to speak with Tumira once more, and then return to Breda to finish the quest. If one would be able to unlock all chests within the allotted time limit, he will receive the achievement of Five-Clawed Cat Burglar.

Reward
Breda will award the player with a New Life Gift Box and randomly a Sailor's Warning Festival Grog along with leveled.

Trivia
The voice actor for Tumira is not the same that voices other female Kahjiit in Online, and is actually the voice actor for most female Altmer. The reason for this is unknown.
