IIRC, there was a line of 'Mechs that were designed as partners or family members to the Marauder. I think the Nightstar and Maelstrom were two of them. Though I could be wrong.
Your not, there was fluff in the original 3058 where it talked about being the last of Marauder series of Podwalkers. Upgrade still says it's related, but not as part of the series.
The last of the Marauder series BattleMechs, the Nightstar was intended as a general support 'Mech for heavy companies. It's primary goal was to protect unit commanders piloting Marauders, who became targets for Amaris troops during early years of the Amaris Civil War.
If you look at the miniature itself, from above which impossible with the TRO picture that only shows from the ground looking up view, it's clearly a Marauder in main body.
Later in the Upgraded TRO, it expands the information but does drop mention of the Marauder series though it seems to just expand on the older book's info.
It does again remind read that..
The Nightstar shares a number of design features with the Marauder...
