Outlanders

Tir McDohl

The hero of Suikoden I and once leader of the Toran Liberation Army, is a wanderer travelling with his servant, Gremio, since the end of the Gate Rune Wars.

Luc

A mysterious mage sent by Leknaat, the Keeper of the Balance, who aids Riou only at her request. He actively works to fight the Harmonian reinforcements granted to the Highland. Luc was previously involved in the Gate Rune Wars and bears the True Wind Rune.

Apple

Once a student of Mathiu Silverberg, Apple is a tactician who was involved in the Gate Rune Wars and convinces Shu to join the Dunan Unification Army. She serves as a secondary strategist for the army.

Leon Silverberg

Leon is a famed strategist from the Toran Republic and is capable of derailing most of Shu's plans. He was previously involved in the Gate Rune Wars and sides with the Highland Army because he believes that they will likely win the war, thus allowing it to end sooner and spare more lives. He is also responsible for summoning the Black Knight Yuber to fight in the war.

Viki

A rather clueless girl who possesses the ability to teleport because she bears the Blinking Rune. She appears before the leader of the Dunan Unification Army within the Erud Forest.

Sierra Mikain

The bearer of the Blue Moon and the Coven Mistress of Village of the Blue Moon Rune. She is searching for Neclord, a rune-using vampire and former ally of the sorceress Windy.

Sierra inherited the Blue Moon Rune in an unspecified event over eight hundred years ago and is the original vampire of the Suikoden world. Overpowered by the rune, she succumbed to feeding off of other human beings to quench her unsatiable thirst for blood. To escape this fate, she left the world behind and retreated into a forest and took refuge in an abandoned residence. As other people wandered into her forest to commit suicide, she ended up granting them immortality with the rune and formed the Blue Moon Village. The village thrived under the rune's protection until it was stolen by Neclord; the villagers became demonic and Sierra, unaffected by the rune's loss, was forced to hunt them down. She meets Nach Lachcke during a hunt for Rean Penenberg, the first person Sierra transformed into a vampire, and ends Rean's life with Nash's help.

Sierra leaves Nash and proceeds to Tinto after hearing of Neclord's presence there. With the help of Viktor, wielder of the Star Dragon Sword, and vampire hunter Kahn Marley, she is able to defeat Neclord and recover the Blue Moon Rune.
