The 3 heroes are doing their regular shit. Adventuring and doing heroic stuff. When they find a old boss dungeon, which is where you rest.

Gabriel: Yo guys! Here! Let's go grind this boss!

Alexander: i- I don't know... This place looks h- hard and scary...

Lilac: well um.. We do need the XP so I guess we should go grind. I think we should be strong enough.

The 3 enter the boss dungeon and get prepared for what they will face!
