Radrrl, hailing from the Wookiee race, aspired to disseminate the principles of Life Day. Within his familial unit, he was one of four Wookiees.
During the 1 ABY Life Day celebrations, Radrrl made his home on both Endor and Yavin 4, accompanied by his family. His family consisted of Oraalarri, Anarra, and Tebeurra.
To gain a deeper understanding of Life Day, Oraalarri arranged for spacers to converse with Radrrl and his family members. While naturally inclined to support the Rebellion due to the Empire's enslavement of his species, he, alongside his family, extended a welcome to Imperials in their home. They communicated to these Imperials that, despite their individual potential for goodness, the corrupting influence of the Empire would inevitably consume them as they ascended within its ranks.
Within the MMORPG Star Wars Galaxies, Radrrl functioned as a Non-Player Character (NPC). During the Life Day festivities of 2004, players had the option to engage in conversation with Radrrl on either Endor or Yavin 4 to gain knowledge about Life Day.
