Additionally, he and Koei's version of Guan Ping both use a greatsword, the only difference being that Garen wields his sword with one hand and Guan Ping using two hands and dragging it along the ground.
Coincidentally, Warring Kingdoms Tryndamere is based on Guan Ping's father Guan Yu. Both father and son served Han warlord Liu Bei, who after their deaths would found the Shu kingdom, heralding the Three Kingdoms period.
When the Exemplar was captured, Garen felt responsible and led the Dauntless Vanguard on a rescue operation.
Garen and Taric are long-time friends from the Shield of Valoran's days in the Demacian military.
Garen was furious at being convinced Taric was wasting his talents as a warrior but he still believed in him.
Garen and Luxanna's father, Pieter Crownguard was a defender during the failed Noxian assault nicknamed Cyrus's Folly. This is likely referring to the same Cyrus who conquered the port city Basilich, which also happens to be the home town of Darius and his younger brother.
