A character in the Trademond smithy, he offers one of the jobs in the game.
Aura can work in the smithy the next day (making her unavailable for any other actions that take up the next day, e.g. longer skill training). The reward is 3 Hit Points, plus a base 50g, increased by 15 for every Star Metal sold to the blacksmith (not anywhere else).
This is not a very efficient use a day (even with always selling Star Metals to the blacksmith, the cost of buying Blessed Water to counter Corruption will eventually outpace the job's earnings). If the player is desperate for money, selling Star Metal to a merchant is an option as it yields much more money than selling it to the blacksmith (although it will preclude available upgrades to Aura's weapons, and some crafting at the alchemist). The job can be useful on lewd playthroughs if the player wants to do more mental changes before reaching the end of the content, while still getting some rewards.
