Silei is the mainworld of the Silei System and the capital of the Independent Coalition of Systems. A founder member of the Independent Coalition of Systems, Silei is considered the centre of galactic affairs. It has been the capital of the ICS for two "stretches": 0 AKR (the founding) until 19 AKR (officially 22 AKR), and from 1118 AKR to the present. The reason for Silei not being the capital of the ICS for most of the first millenium AKR is the Catastrophe of the Star, which killed off the planet's population, with repopulation only beginning in 953 AKR. After the Catastrophe, Capital was colonised with the express intention of making it the ICS capital, which it was made in 22 AKR (the ICS Senate had resided on Aqualis temporarily).
