Leyshrine Surge - New Player

[Britta]

I'm a new player and at level 60 within a few days but I don't know much of what I'm doing when it comes to the lore of the game. I happened to activate a Leyshrine by crafting a focus alter. I didn't know what would happen. So the thralls spawned and I fought each group around the Leyshrine and they kept spawning... I see no end to this (killed each group about 4 times). Do I leave the Leyshrine active? Do I do something to turn it off? I wasn't able to access the center panel in the building after crafting the focus alter. Pressing E to interact didn't actually do anything like the first time when I crafted the alter so... what do I do now?

In the meantime, I just returned to my base but would like to know what I do now and also, do I activate all of the Leyshrines around the map?

No.
No.
You do not have to do anything, it will shut down after the last wave or if the Maelstrom comes.
If you want, you can.

Point to leyshrines is to power them up first to a specific point before unleashing them.
So they spawn T4 thralls that you can enslave and have a high quality line up of workers.

Thanks for the responses. I crafted one focus alter with 10 hardened steel bars and then I flipped the switch. I fought each of the three podiums(?) a bunch of times but I saw no end. Do you know how many rounds I should expect? I was expecting a last wave but decided to leave instead. It did go away after the Maelstrom, yes. Knowing more now, I'll be prepared to collect thralls.

It depends on how much chaos you put in it. (How many rune lights around the stairs/frames above the glass map.)
But, “If you give a man a fish, you feed him for a day. If you teach a man to fish, you feed him for a lifetime.”

I read this webpage before, thank you, but it didn't answer all my questions. I should be ok now, thanks to you both :)
