+ Wonderfully thematic and well-presented

+ 'Unsettling questions' :P

+ Excellent advice on foreshadowing, something that I think a lot of GMs could learn from (doing it on the fly can be really tough, but it's a great skill to learn and hone)

+ Stat blocks are indeed the death of tension

+ Contrasting size is on my mind with PICO, but I suppose it's actually just as important with Leviathans (especially when you have everything between Old Ornail as 'really big squirrel' and the potoo as 'living island')
