There are more than two kids selecting the starters at your town.
that is what prof oak wants you to think. The vid was also about what happens to the pokemon that basically aren't very good that never get used. Vid title was pokemon hoarder I think. You can look it up but it is distrubing.
but there have already been some graveyards. -lavender town pillar -that pillar north of skyla's town (i think route 7?) and i think there were more but already 2 of them is enough to say that another graveyard isnt unrealistic. also, i think where the carnac stones are, there is a kind of graveyard AND we will find honedge there. 1. it was shown in the vid right after that location was explained 2. its a ghost in the sword of a long dead warrior.
