I have just the one creature type to review this time but there are a lot of them. These are the Void Spiders from the Shadows of Brimstone core set - City of the Ancients.
Inhabitating the space between the Void and reality, these scurrying beast infest virtually every world their portals open into. With six segmented spiny legs and two large mandible claw arms, Void Spiders can scale any surface and are often found nesting on the walls and ceilings as well as the floor. On the underside of the creature is a large mouth, lined with jagged teeth and articulated jaws within the body of the beast. Void Spiders' primary form of attack is to lunge at their prey and get on top of them, using these under mouths to chomp and tear at their victims. Many Void Spiders secrete a Void Venom, paralysing their target before cocooning them in sticky webs to feed upon slowly.
The first photo shows them from the front, which is where their mandible arms are located. This photo shows them from behind. These figures are one-piece castings and come without bases. I did consider gluing them to bases but then decided they were better left as is. They are roughly 40mm in diameter and are 15mm tall.
Here is a group shot showing all twelve Void Spiders. Their pale grey colouration is great camouflage on the arctic world of Targa. I leave you with this cool piece of artwork taken from the City of the Ancients adventure book.
