This is a quest given by a lord of a friendly faction that is not marshall. You must be level 6+, have 100+ renown and have enough space in your party. It consists of training five to eight tier 1 troops provided by the lord until they reach the target type he requests, then giving them back. The troops you give to the lord do not have to be the same men he gave to you, you can even finish the quest immediately if you already have the troops he needs in your party. On failure, you will incur a debt of 100 denars with the lord, as you had been paid in advance.
