Hi troopers!

I have decided to return to the game after a longer break.
I can see there's quite many new features, the dungeons opened with keys being one of them. So, seeing as there's a story continuation in the new LoL levels 11-15, I immediately tried that. I beat 11 & 12 without a problem, but when I got to 13.. that's where the frustration began.

So I headed for the forums and found this thread. Read it from start to finish - all is nice and cool, but it seems that almost every post here suggests the same sets of talismans - Orbits, Vipers, Singularity etc. Of course I have none of them and it seems there's no way to obtain them anywhere.

So here is my question - can these talis be earned somehow? Do they drop anywhere? For how long are they already in the game? And most importantly - does anyone have some good workarounds? I have Alex and Charlotte, can buy Warrior Lord of Light as well (and will probably do), I also have Killer Prime. The main problem for me is the lack of talismans.
