“I may not look it now, but I'm the son of a wealthy Carcino merchant. I believed that you could move the world if you but had the gold. Money was everything, and with money, nothing was beyond my reach! I adored money! I loved money! You see?”
—Rennac talking to Dozla in a support conversation
Rennac is first seen in Chapter 4 along with Dozla and L'Arachel. The three are standing atop a large rock incline and see the large group of monsters below attacking people. Dozla and L'Arachel say they must rush down the slope to aide the poor people but Rennac suggests they find a safer way down as opposed to charging down the cliff and getting injured.
Rennac was originally hired by L'Arachel to escort her to Renais. However, despite her wealth, she never actually feels the need to pay him. After his initial appearance in Chapter 4 where he talks very little, he is spotted on several occasions with, or hiding from L'Arachel, and complaining about her. In Eirika's Route he can be found in a house hiding from L'Arachel and he hands over an item to a character to ensure they won't reveal where he is hiding.
In Chapter 14, he appears as an enemy unit (either hired by enemy troops in Eirika's path, or acting freelance in Ephraim's), although in his dialogue he shows no intention of actually fighting. Rennac is recruited in Chapter 14 in either Lord's route by paying him 9,980 gold with the main lord, or by talking to him with L'Arachel. If L'Arachel talks to him he'll complain and resist but eventually crack and agree to fight with her. Rennac is apparently also an excellent dancer. When he was young, he would dance with his father's female associates in order to entertain them. His dancing skills were also shown in his B support conversation with L'Arachel where he danced with her. He often tries to disobey L'Arachel and escape from her, but somehow he keeps coming back.
Rennac is one of only two 'Thief' Class units, although he is a pre-promoted Thief in the form of a Rogue. The other Thief unit is Colm, who actually starts off as a thief and can later be promoted to either Assassin or Rogue. Most choose to promote Colm to an Assassin as there is no pre-promoted Assassin, and Rennac is already a Rogue. The Rogue class is the only one that can open doors and treasure chests without a Lockpick item, Thieves and Assassins in The Sacred Stones requiring a Lockpick to open doors and chests.

Rennac fills the role of a lategame prepromoted thief, and he can fill all the utility needs of his class right from his join time. He can open chests, has a perfect chance of finding items in the upcoming desert maps, and he can steal items off of enemies very easily. His bases are extremely poor for his level, and he is sword locked, which together make him an incredible weak combatant, but for whatever duties a player has need of a thief for, he can handle them easily.
“Great. This is just what I needed...”
- Rennac, Rich "Merchant" (豪商盗賊 Gōshō tōzoku)
L'Arachel summoned Rennac back to Rausten, and he was forced to return. He was never able to escape his service to the self-centered princess who became queen. Admittedly, he didn't try very hard.
