Use care please: Outside the GLASS sword container (please be careful of the contents too, thanks) in the cache is a zip lock for the log with three pencils to sign your name with your fav house: Lannister, Targaryen, Baratheon, Tyrell, Greyjoy, Stark, Bolton, Tully, Martell, Mormont? :)
Can you guess the sword's name? See hint for answer.
Hints and spoilers in the photos. Have fun!
