During the Rogue Trader activity, players will ask Aubury to supply Ali Morrisane with runes, and Aubury will agree. After the completion of Rogue Trader, players might get cheaper runes from Ali Morrisane, provided they are able to solve a puzzle.
As of 2 September2009, with the personalised shops update, Aubury now offers 30 free air and mind runes if the player trades him, much like his friend Mikasi of Lumbridge used to. The runes restock when bought, but rather slowly, at least half an hour's time to fully restock. The runes will not be restocked until the period of time has passed, even if you should change into another world, though your log-out time does count for this restocking period. After the September 2009 update, Mikasi no longer gave out any jobs or runes, but she had heard of Aubury's free samples and suggested that the player go there to seek such supplies. Mikasi has now been removed with the 2012 Evolution of Combat update.
If you ask Aubury, at the 2011 Christmas event banquet, how his shop has been doing, he will say that "It is a lot quieter these days" and "Teleporting people to the rune essence that many times in a day gets tiring". This is a reference to the recent bot nuke.
