The next downloadable expansion to Destiny is called House of Wolves and is scheduled for May, claims a new rumour.

Redditor megamanexe4 claimed to have access to the expansion. He posted images and information related to it. House of Wolves will contain a new raid, a new strike, new crucible maps, and new weapons and armour.

Gear will now have a maximum light level of 39, implying that vendor gear will once again make high-end raid gear a redundancy.

Nightfall events will be increased from level 30 to level 32.
