I swear I remember reading somewhere that someone realised that the darkness wasn't inherently evil, that it destroys because it must. I tried looking through the marasena lore but couldn't find it. It sounds like the traveller and the darkness are two sides of the same coin. Aunor thinks this is just us listing for power but if anything we pursue darker powers because what we know is changing as we learn more. Why can't we use the darkness? Because a group of people believe it only to be bad and to use it would make us bad? That's BS, the use of another unknown power doesn't make it bad. Dredgen Yor was bad because of what he did with the power of the Thorn. The Shadows of Yor follow in his footsteps, no wonder Shin went after them hardcore. But he trusts us, he sees us walking a fine line and realises that we plan on continuing to use dark weapons and powers but is willing to risk that because of who we are and what we've done. We are a beacon of hope, much like Dredgen Yor was before his fall, Shin promised us he'd be there if we need to be stopped and I expect nothing less. He's willing to let us make our own choices, he knows there's more to this war than light and dark, he sees shades of grey. The biggest difference between him and the Vanguard/Praxic Order? He's been in the field since the Dark Age, the others sit in their city and only hear about what's going on out there, they know nothing compared to Shin.

You can not have light without the dark... it is balanced. If only Bungie could adopt this approach. There is order in chaos.
