Horizon Signal: how to continue? (SPOILERS)

[Mitchz95]

I've been doing the Horizon Signal chain (which is awesome BTW) but I haven't seen any story progression in a while and was wondering if there's anything I have to do to trigger the next step.

Here's what I've seen so far:

- The events near the black hole (losing a science ship, sacrificing another scientist)
- The Messenger (all pops on my homeworld turned into its species)
- Admiral from the future forces me to kill her in space combat
- New colony has too many pops, some pre-built buildings; original colonists go missing
- Present version of aforementioned Admiral has died (but rumors of them still sneaking around somewhere)

What do I have to do to continue the chain? No spoilers, please!

You need to have an obversation post orbiting a planet populated by a pre ftl species. They will start to do rituals just make sure you don't get involved

I got to this part and didn't interfere but I haven't seen anything since. Advice? It's been almost 10 years.

The observation post thing is like a sidequest more than anything. You should have some new research options available, take them and build the things they let you build.

Thanks, I'll try those.

I built two Observation Posts and a Spiral-Feed Power Hub but nothing has happened after ten years. Is there something else I'm supposed to build?

Should have three different special buildings built

Ah okay, I just have the one so far. Will research the others and get them built. Thanks.

You don't actually have to do this to complete the chain. At least, I didn't have to when I got the achievment. What the OP is waiting for is the other two buildings. One is a level 3 tech, so it may take a while until he draws the tech card.
