We need siege weapons to prepare for a war.
Strong ones.
We need sturdy wood to make those.
Look at the Trina Knights fighting Saunils now.
They're sacrificing the whole Treant forest to make siege weapons.
I heard Treant wood is the hardest of all wood.
We can't just sit down here and let the secret slip away like this.
Don't you think we need to study Treants too?

Humans make so many weapons.
Where they did get all these Timbers?

There's someone who hates our plan.
Like the Saunils...
but more powerful.
Hope it's an easy target like the Saunils.
