BTW as for your diagram, I would probably go with tikz directly rather
than with forest. Like this (polishing needed):

\usepackage{tikz}

...

\begin{tikzpicture}
\draw[anchor=mid]
      (0,0) node (a) {a}
      (1,0) node (b) {b}
      (0,-1) node (c) {c}
      (1,-1) node (d) {d};
\node (e) at (1,-2) {e};
\node (f) at (1,-3) {f};
\draw (a) -- (c);
\draw (a.south) -- (d.north);
\draw (c.north) -- (b.south);
\draw (b) -- (d);
\draw (d) -- (e);
\draw (e) -- (f);
\end{tikzpicture}
