You decide to search the House Head's office. What you find there is very surprising, on the desk is a golden cup, modestly jeweled, with two handles and engraving of a badger on it. It is also radiating powerful dark magic, although feels broken, incomplete. Perhaps you should find the rest of the set? No, keep us hidden
It would also completely block tracking signal, for as long as the cloak remains inside. You might have been worried about the cloak becoming corrupted, but as long as it remains inside the Bag of Holding and doesn't directly touch the cup, you will be fine for at least a few hours.

[Gained Item: Corrupted Cup of Helga Hufflepuff]
[Gained Long-term Goal: Collect the Horcruxes]
A.N. Let's just say that the story of how the Hufflepuffs took the cup from Bellatrix Lestrange's vault involved (magical) secret agents, decoys, muggle-style fake identities, and at least one dead goblin.
