I'm not allowed to say where I got this, but the documents make it clear: matrix has been on the goblin board's quarterly agenda since 1973.
A goblin tabletop GM, asked to stat matrix, produced a stat block with one ability ('exists ominously'), no listed weaknesses, and a CR of '?'. Their players consider this fair.
The threshold Manifestation
After much deliberation (and several stolen snacks), the Goblin Council has issued a formal statement on threshold: 'It is what it is, except when it isn't, which is most of the time.'
