Yeah I just read through it and I agree with Barinellos -- it hits some simple notes that we don't really have a lot of in our Archives. It carries a silent somber tone without going for the gut punch. I think it's the stronger because of it, not trying to over-step it's bounds just to evoke a response in its audience.
Raven also brings up a good point that makes your piece stronger as well: goblins in M:tG are oppressed, the brunt of jokes, enslaved,
just stupid, etc. Why this affects your piece is severalfold. First and foremost, you bring a touch of humanity to these goblins, especially Masked Goblin of course. Secondly, the clear implications of the world you have built up around them places it perfectly within Magic expectations: goblins as a persecuted race, murdered out-of-hand without thought of their feelings or culture, possibly even eradicated completely and left extinct, no care even given to give the bodies a proper burial. It really gives your piece the humanizing strength that only Masked Goblin is from here, that he managed to escape, that he comes back to pay respect to his dead family, and that Fat Goblin and Tall Goblin come along with him.
I'm assuming that Masked Goblin's companions are 'walkers themselves, which also implies the strength of the bond they share, that they would accompany him for this personal journey, despite becoming increasingly uncomfortable during their stay and not having the emotional connection to the place that he does. And they do so with minimal complaints, mostly just waiting for the appointed time to arrive.
Then there's the realistic presentation of the world. You don't get heavy on exposition of unrelated portions of the plane, you just describe the location that the characters are experiencing with a little touch of the emotional past that Masked Goblin himself experienced. You make it very clear that this is the just the small, localized spot these characters are experiencing, and being (forgive me for saying this) simple goblins, it works in such a totally coherent way without seeming overly-simplistic.
I can't give you more than two thumbs up for this, but if I could I would.
