I came to think about this recently. It is highly convenient for the majority of the species from the current cycle that the accessable Mass Relays of the Cluster are located directly in the homesystems of these species, isn't it?
There are many dormant Relays throughout the galaxy according to the lore, but it's really suprising that the most advanced species do have an accessable Relay right in front of them.
This bears the question:
Is there really only one Relay per Cluster? If so, what if a sentient space faring species evolved on, say Alpha Centauri and not Sol III, they had to search the whole Local Cluster and would've to stumble across the Charon Relay just by chance, wouldn't they?
From the perspective of an AI that is trying to maximize the efficiency of the harvest, this is illogical and a waste of time and ressources.
If there is a Relay in every system in the galaxy, well good luck in repairing them all..... I'm getting headaches just thinking about the tedious mineral scanning to collect all the Eezo needed for the billions of cores.
Makes not much of a sense either.
So I think, there is a significant number of Relays per cluster, but they are movable just like the Citadel, and the Reapers do reposition them, say 2 cycles in advance, towards systems where highly developed species can be found 100k years later.
That said, the Charon relay was repositioned after the Harvest of the Inusannon and their respective cycle towards the later to be known Sol System, just like they did with Palaven, Surkesh, Tuchanka, Rannoch, Thessia aso.
This way, the follow up cycle (here Protheans) could stumble across those lesser species too, without the Reapers raising suspicion about their true intentions. Otherwise the Mars Archives would've been of Reaper origin, which they clearly aren't.
What do you think?
What was everyone’s weapons they used in the campaign of mass effect 3. Rate which ones were the worst or the best. What was your “bread and butter” weapon?
My loadout Started off with the Cerberus Harrier, (Rifle) Indra, (Sniper) and Phanlax. (Pistol) Then I had Phaestron, Indra, and Phanlax. I replaced the Phanlax with the arc pistol, and then for the Citadel DLC onward I had the Lancer, Indra, and Arc Pistol.
