Oreasha was confident and direct in her actions, not allowing subordinates to slow down or impede her retrieval of what she desired.
Oreasha wielded a single blade and barbed whip when she decided to personally engage in combat.
In the Year of Three Ships Sailing, 1492 DR,[note 1] Oreasha entered into an infernal contract with the mortal Krydle of Baldur's Gate. As Bel had taken great interest in the half-elf rogue, Oreasha agreed to protect Krydle's friends while they were trapped in Elturel during the city's descent into Avernus and free Shandie from the clutches of some chain devils, in exchange for his soul to be delivered to Bel. The mortal Krydle agreed to this deal, and had seared upon his arm a reminder of their "soul pact".
- Canon material provides two distinct dates for the events described in Baldur's Gate: Descent into Avernus: the adventure itself, described in chapters 1 through 5, takes place "fifty years" after 1444 DR (1494 DR), according to events mentioned in pages 7 and 47, while the Baldur's Gate Gazetteer describes the city as of 1492 DR (p. 159). It is possible that the designers made an approximation for "fifty years", even though it is stated in an infernal contract. The lead writer for Baldur's Gate: Descent into Avernus later confirmed that the adventure takes place in 1492 DR, and the sequel to the adventure, Baldur's Gate III, also claims that the current year is 1492 DR in multiple places.
