  text: We study representation finite $K$-rational quivers over fields of characteristic
    $0$ and their indecomposable representations, exploiting that all Brauer obstructions
    for descent of representations are trivial in this case. Contrasting the tame
    case, we give an example of a simple quiver of wild representation type, where
    we realize every possible Brauer obstruction of a given Galois extension $L/K$
    in the category of quiver representations over $L$.
