Dark Mage

The Dark mage is located at the centre of the Abyss. He can repair damaged pouches for free and give back an Abyssal book and/or Small pouch to the player if lost. It's not required to bring him the pouches, because he can repair them even while they are in the player's bank. An alternative is to contact him with the lunarNPC Contact spell however this spell will only work if the player has met the Dark mage beforehand.
