I am sorry to see an informed & erudite discussion (on my part in the main, admittedly), relegated to 'Mirth'. Sadly this has always been the fate of such cutting edge speculations
I intentionally provided quotes, & references to Tolkien's works, to back up my thesis that Elves are innately prone to combustion & a particularly useful fuel source. I think its clear, now, that the reason for the tiny number of Elves in Endor by the end of the Third Age is due principally to, on the one hand, their usefulness as a source of domestic fuel &, on the other, to SEC (Spontaneous Elven Combustion) due to over excitement or stress. Incidents of IEC (Intentional Elven Combustion) also seem to have occurred in battle as a deliberate act (Elves as WMD's is an area I think is worthy of further investigation. Morgoth's invasion of Beleriand was probably down to his desire to locate & neutralise this threat to Angband.)
I hope this move to Mirth will not result in the thread being taken over by sillyness & jokey comments.
Thankyou.
