"The Zelban you summoned is far stronger than all the rest. You should be thankful to me."
"A Summoner making me strong... Have I really strayed so far from my fencing days in La Veda?"
"I've once again become stronger. It seems the burdens I have born have finally yielded me strength."
Swordsmen by the name of Zelban have appeared several times throughout history. This particular one took part in the great battle with the gods. It's said the Zelbans before him preferred to fight alone, but he was different and instead fought alongside his comrades. There are many theories for why he did so, but a major document has him recorded as saying, "I didn't plan to fight with them. I simply got caught up in the same battle as them."
