These are Tristan and Caerwyn Sanguinus. They're twins, both of them paladins. Tristan is protection, Caerwyn is retribution. In game I respec them as the need arises, but for RP purposes, they are exclusively prot/ret. They were trained as Knights of the Silver Hand until after the Third War at which point they remained as Blood Knights.

Tristan is the one facing us directly. He is the gentler of the two, and very talented, though not as powerful as Caerwyn in terms of ability. He is the one whom one would perceive as noble or honorable. He doesn't discriminate; he extends his protection to anyone and everyone who may need it, which causes him to stand out amongst his Blood Knight brothers and sisters. Shortly before M'uru was kidnapped (the second time...kidnapped from his kidnappers) and the Blood Knights were pledged to A'dal, Tristan was close to defecting as he felt his morality was in jeopardy.

Caerwyn, conversely, is bloodthirsty and deeply married to his concept of justice. He is extremely powerful, and this strong commitment to what he perceives as "just" is the foundation for that power. After the Third War is when Caerwyn developed much of this, feeling betrayed by the Alliance. He is/was very patriotic and very committed to Kael'thas' cause which ultimately became the downfall of this champion of the sin'dorei. Likely due to this deep-seated passion, Caerwyn was also very promiscuous in his youth, and later, as a Blood Knight he met and fell in love with a rogue named Valerion Sunlancer (whom I just cannot seem to draw =\). That relationship would last quite a while until Caerwyn's growing insanity put an end to it all.

Yeah so.
