In the camp at the Winterfell Northern Gate, Yoda was on the Airship, watching the gamers as they transported the equipment to Winterfell. According to them, they were transporting the loot back to Eternal Kingdom via the Teleport Portals.
It was an eye-opener for Yoda. From what he heard from Moroes, the citizens of Eternal Kingdom could revive endlessly due to Lord Sherlock's power. They were fearless legendary warriors.
Yoda thought Moroes was bluffing.
He saw the green-skinned creatures covered in blood, but they were without fear. During the Area No. 10 Battle Campaign, he saw the courageous Goblin who was laden with bladders, but he was skeptical of the creatures having unlimited revivals.
Was Lord Sherlock the Hades Lord? Or the son of the Hades Lord? Even the Hades Lord wouldn't allow that many creatures to have unlimited revivals!
