The saga of the trees of harmony has been a series of rare arcs for a narrative structure that really becomes questionable more than anything for trying to put several characters in 50 pages except for the first arc which was that of the zebras.
 
But with # 100 came the knights of harmony who turn out to be the villains of the saga despite carrying harmony in their name and other interesting things is that they are chimeric entities from which I can intuit that the 6 each has abilities that are related with fragments to alter reality such as space-time, gravity, energy, and as in the case of her, matter. Being able to deform the physique of the people who invoked her as mentioned in # 100.
 
And after seeing that Ceridwen enlarged a crow, why couldn’t she modify bodies in other ways? And of course the victim was Eris for being the weakest draconequus of the 3. And yes, it seems that there is a history with the draconequus because of how she looked in # 92 and recently in # 100.
 
Meanwhile, isn’t weird that an celtic name is used for a creature that looks like an quetzacoalt?
