Rilbedur Tjar is a level 1 data center agent for Minmatar COSMOS. Even trhough he is located in Engosi outside of the Minmatar COSMOS constellation the mission from this agent is still required for Minmatar COSMOSO.
The Graduation Certificate
| Type | Courier |
| Objective | Retrieve 1x Minmatar Graduation Certificate (0.1 m3) |
| Rewards | Minmatar Graduation Certificate (signed) and faction standing |
This mission can be requested from three agents (West Ludorim, Rilbedur Tjar, and Albedur Vatzako) and thus can be completed three times. The ISK value of the reward is low, but it also awards faction standing.
The mission is simple: fetch one unsigned certificate from a nearby station and the agent will sign it for you.
The mission texts suggest that this was supposed to be the starting mission for the Shaman Secrets mission chain, but this connection is not implemented in game.
