Everyone Has a Castle: I Choose Elves to be in My Army

It was an age where people could freely travel to another world and become a lord themselves. They could participate in wars between races, raise their army and create their empire.
Through random distribution, Gale received land where he could choose to summon a unique battle unit of God Tier potential.
“I have summoned the trolls! Who wants to fight me?”
“Trolls? I have summoned the Angel of Darkness!”
“Hah! My summons are the sky dragons! They have the potential to reach Tier 9!”
Looking at the messages, Gale turned to look at his army of Elven Empresses, golden behemoths, and gold dragons and thought to himself, 'Should I join their conversation?'
