A new subclass, destination, and info on the next season have seemingly leaked before today's Destiny 2 showcase

pcgamer.com:

In advance of the upcoming Destiny 2 showcase later on today, lots of Lightfall (opens in new tab)images have surfaced via the Destiny 2 leaks discord(opens in new tab). Before we start, though, if you don't want to see any spoilers for Lightfall or Season 18, which also starts later today, you should probably leave now.

Most notably, the supposed leaks include Neptune, a new destination that honestly couldn't look more cyberpunk. There's also a glimpse at what looks like the next subclass, with the guardians wreathed in various forms of green energy. Rumours about «Strand», which is thought to be Destiny 2's second darkness subclass after Stasis, have been knocking around for a some time(opens in new tab). It now seems certain to be revealed in today's Showcase. 

What's less clear is whether Strand will lean into the 'poison' effect used already in Destiny 2 by the exotic weapons Osteo Striga and Thorn, as had been predicted by many players. According to the more recent leaks, the subclass will be heavily movement based.

If we are heading to the watery planet of Neptune in Lightfall, according to the leaks it will be to try and stop (big bad) The Witness from stealing a powerful artifact from a previously unseen alien race. Either Calus, or a new disciple similar to Rhulk, judging from the leaked key art, seem to be in command of the Witness's forces.

The rumours also suggest that these new friendly aliens teach the guardians the new subclass to help them in the fight. The introduction of a whole new alien race would be pretty wild, since it'd be the first proper new faction since the introduction of the Scorn in Forsaken back in 2018.

An Epic Games crossover is also reportedly on the cards, with three sets of armor
