Once those are unlocked, you start on Lore (pets) and Destiny (big AOE buff). Judgement is a giant GET hosed nuke available to all archetypes every 90 seconds, Interface is a proc that applies to all of your powers. Once you unlock it, you start unlocking the next two: Judgement and Interface. Of course, the Alpha slot isn't the only one. You can make as many as you want, but getting all the bits can be a pain in the rear end, so choose wisely but don't stress about loving it up because you can fix it later.
#City of heroes lore incarnate tsoo upgrade
A list is here, and also in-game, but the short version is "it is a universal enhancement that applies to all of your powers." As you upgrade it, it provides a bigger bonus and/or more bonuses, and when you upgrade it to tier 3, it gives you a Level Shift: you count as level 51 for all combat calculations that check level (damage, accuracy, effect duration, et cetera), but are still 50 as far as rewards are concerned. Once you get your Alpha slot unlocked (again, there's various ways to do that), it is time to make a Thing for it.

To be less cagey about it, the specific thing is the mission Lady Grey gives you to retrieve the container and deal with Captain Holtz, and the reason is you have to fight The Honoree and Captain Holtz at the same time, and they're both AVs, although they can be scaled down to EBs. Since this is probably your first, you have two realistic ones: "keep earning XP and it'll happen on its own" or "do the Alpha Unlock thing in Ouroboros with Mender Ramiel." I suggest doing the Ouroboros thing at least once, with the caveat that at one point you're told "hey, this is hard, bring friends." I suggest bringing friends because they aren't joking. To unlock your Alpha slot, you have a few options.

There is no more power to be had from them directly, but it gives you the currencies you need to make the stuff that does make you more powerful. They're just more levels after 50, and you get rewards as you get them. There a post somewhere on level 50 stuff? Incarnate, veteran, hell even just figuring out which enhancements to use is a bit overwhelming for my punch nazis with a lightning fist game.
